Today on Hackaday Dictionary, we’re going to talk about the two basic types of control systems: open-loop and closed-loop. We’ll describe the differences between them and explore the va… ...

Of course, a “simple” open-loop control system can mean a steeper learning curve. It’s not easy to learn to drive a manual transmission.

For example, traditional step motor systems run in open loop control. That means the drive electronics continuously supply current to the motor whether or not the load is demanding torque.

In real control systems often a synthesis of open and closed loop, feedback and feed-forward, SISO and MIMO controllers are used in sequential, hierarchical, nested or networked combination.

The open-loop heating system has some advantages, including design simplicity and ease of maintenance. With only voltage applied to a heat source, this method does not require an elaborate control ...

The first randomized phase 2 trial to evaluate outcomes for spinal cord stimulation finds an advantage for an investigational closed-loop system over open-loop.
